The death toll from a suicide attack inside a local mosque in the northeastern Nigeria town of Mubi on Tuesday has risen to 58, a senior health official said on Wednesday.

Ezra Sakawa, principal medical director of Mubi General Hospital, told reporters that the hospital received 48 victims, eight of whom died while receiving treatment.

Local police put the death toll at 50 on Tuesday, saying the dawn attack was perpetrated by an unidentified teenage boy who set off the suicide vest he wore to the mosque in a suburban town of Mubi in the northern state of Adamawa.

The teenage attacker detonated the bomb immediately after the prayers inside the local mosque.
